[gtkextra] linking gtkPlot in a GTK+ application

[Laura H. de la P. <la...@gm...>]

Hello,
i'm trying to add a plot in my application.

Compiling i get:

..../Observation.cc:62: undefined reference to `gtk_plot_get_type'

I have tried to modify Makefile.am of /src/ without success.

Can anyone help me please?

Thank you!
